I am really surprised and disappointed to hear a breeder let alone several tell you they are good with kids
but then stick around here and you will see how many people have 10 lb yorkies that were told they would never get over 4 lbs
. I am sure if you try you can get it to work but be prepared to tell you 2 year old until they are probably 5 NO an awful lot. It will be the nature of your baby to want to hold and cuddle the yorkie like they do with a stuffed toy, only this one might bite if squeezed to hard, but then I guess that might teach the child a lesson. Yorkies also need a fair amount of grooming, everyone I have had needed a bath about once a week or they would be pretty smelly, their teeth need regular brushing as well.
Also be careful around doors, kids like to come in an out a lot and a dog can easily get let out or get caught in the closing door, I have no kids and have to be constantly aware of this myself.
